Windows DNS Server. How to make a policy for a subnet?

Question

Domain Name System

Good afternoon.

There is a resource let's say example.com
I want to make a DNS policy so that
for the subnet 192.168.100.0/22 ​​there is an A record of example.com (with an external IP),
and for the rest there is an A record of example.com (with an internal IP).
I did according to this manual https://wpconfig.ru/?p=1336

But it turned out that now users 192.168.100.0/22 ​​see the example.com entry as it should with an external IP, but they do not see the rest of the entries in the zone.
How to make it so that in fact all A records in the zone are seen and the difference was only the A record of example.com?
thanks in advance
